Embodiment Construction

[0018] Such as Figure 1 to Figure 7 As shown, a special compact helical gear structure can better cooperate with the assembly mechanism during installation, and the connection is tighter. The structural strength is better during use and the service life is longer. It is more convenient in the process of assembling, and the installation efficiency is higher. It includes the cylindrical body structure 1, which is the main structure of the whole part. The upper cylindrical surface of the main structure 1 is provided with a helical tooth structure 2, which is used in conjunction with other helical tooth structures. The central position of the main structure 1 is provided with a cylindrical central assembly hole 3 that runs through the entire part, and is assembled and connected with the assembly shaft. The center of the upper end surface of the helical tooth structure 2 is provided with a cylindrical protective boss 4, which can effectively prevent the helical tooth from collid...

Abstract

The invention relates to the technical field of gear parts, in particular to a special compact helical gear structure. The technical scheme adopted by the present invention is: comprising a cylindrical main body structure, a helical tooth structure is provided on the upper cylindrical surface of the main structure, a cylindrical central assembly hole penetrating through the entire part is provided at the center of the main structure, and the upper end surface of the helical tooth structure The central position is provided with a protective boss, the inner cylindrical surface of the central assembly hole is provided with a central axis positioning column, and the lower end surface of the main structure is provided with two evenly distributed arc-shaped locking bosses. The outer cylindrical surface of the structure is the same plane, and the inner side of the clamping boss is the same plane as the cylindrical surface of the central assembly hole. The invention has the advantages of better tightness when used with other gear structures, stronger anti-fatigue ability during use, higher strength of the engaging position, longer service life, and better transmission effect during transmission. Well, it is more convenient during the process of making assembly connections.

Description

technical field [0001] The invention relates to the technical field of gear parts, in particular to a special compact helical gear structure. Background technique [0002] A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. It is a toothed mechanical part that can mesh with each other. Helical gear is a kind of gear structure. Helical gear transmission is composed of two helical gears meshing. It is characterized by low vibration, low noise, high energy saving, and saves space, so it has a wide range of applications. [0003] The effect of the helical gear in use is closely related to the stability of the assembly. When the helical gear structure is fixedly connected, it is generally assembled on the bearing, and connected together by setting the assembly boss. Since the helical gear produces a relatively large force when it starts to rotate, cracks often appear at the position of the assembly boss after long-term u...
